The wheel comes off a jet as it takes off!

When you get on board an airplane for a fun, relaxing vacation get-a-way, the last thing you think about is the wheel coming off the airplane! That is exactly what one passenger captured happening as the plane he was on took off from Canada. Air Canada Jazz Dash 8-300 #AC8684 to Saguenay lost a wheel as it departed Montreal yesterday. Sparks were seen prior to separation. The flight returned safely to Montreal. Video shows departure & wheel falling off, passengers being calm and a smooth landing. Remind me to never look out of the window of the jet I am flying on. Where is the exit?
